Perma-Fix offers a thermal desorption process which is used to remove the free organic
fraction from inorganic solids that contain volatile or semi-volatiles. This process
uses a combination of temperature (up to 625°F), vacuum and carrier gases (e.g.
steam & inert gases) to aid in the separation and desorption. This process is
performed in an oxygen free environment. The desorbed constituents containing less
than 2 ppm PCB’s are then treated via direct chemical oxidation or combustion. Desorbed
liquids containing >50 ppm are then prepared for shipment to the DSSI facility
for combustion. The residual solid waste resulting from this process typically requires
stabilization to render it amenable for disposal.
The DSSI facility operates the only commercial mixed waste combustion unit in the
United States with TSCA treatment authorization from the EPA Region 4 to manage
TSCA regulated PCB contaminated radioactive wastes. This authorization is the first
and only commercial outlet for radioactive PCB waste treatment and disposal available
to both Government and Commercial generators.
